UNE-EN ISO/ASTM 52921:2017

1.1 This terminology includes terms, definitions of terms,

descriptions of terms, nomenclature, and acronyms associated

with coordinate systems and testing methodologies for additive

manufacturing (AM) technologies in an effort to standardize

terminology used by AM users, producers, researchers,

educators, press/media, and others, particularly when reporting

results from testing of parts made on AM systems. Terms

included cover definitions for machines/systems and their

coordinate systems plus the location and orientation of parts. It

is intended, where possible, to be compliant with ISO 841 and

to clarify the specific adaptation of those principles to additive

manufacturing.

NOTE 1 The applicability of this standard to cladding has to be

evaluated. Discussions are under progress.

NOTE 2 Non-cartesian systems are not covered by this standard.

1.2 This standard does not purport to address all of the

safety concerns, if any, associated with its use. It is the

responsibility of the user of this standard to establish appropriate

safety and health practices and determine the applicability

of regulatory limitations prior to use.
